Description

Technical Field

[0001] The present invention relates to the field of intelligent construction technology, and in particular to a support leg pre-adjustment method suitable for rapid deployment of a shelter. Background Art

[0002] The existing types of shelters include: medical shelters, military shelters, civilian shelters, emergency shelters, etc. In the general deployment and implementation of shelters, in addition to the need for pile foundations or cement floors for placing shelters, there are also adjustable legs for deployment on non-hardened sites. However, for large-scale shelter building clusters, there are often thousands of legs. If leveling is performed on site, it is time-consuming and labor-intensive, affecting the deployment progress. Summary of the invention

[0003] The purpose of the present invention is to provide a support leg pre-adjustment method suitable for rapid deployment of shelters in response to the above-mentioned problems. The height of the shelter from the ground is calculated based on GIS+BIM technology, and the support leg height is pre-adjusted in advance in the factory.

[0004] The technical solution of the present invention is as follows:

[0005] A method for pre-adjusting support legs for rapid deployment of shelters, comprising the following steps:

[0006] Obtain oblique photography GIS data of the target site for rapid deployment of shelters and build a GIS model;

[0007] The GIS model is transferred to the lightweight fusion engine for lightweight processing;

[0008] The BIM model is transferred to the lightweight fusion engine for lightweight processing and superimposed with GIS and BIM models;

[0009] Use Cesium to calculate the height difference of the GIS model terrain within the BIM model projection range. If the height difference is within the range of the support leg lifting adjustment, use the physical center of each support leg as the reference point to calculate the distance from the ground to the bottom of the warehouse at that point, so as to obtain the height that the support leg should be adjusted to.

[0010] The height of each leg is pre-adjusted and numbered in the factory according to the calculated results, so that it can be quickly called up and adjusted during subsequent deployment.

[0011] Furthermore, the step of transferring the GIS model to the lightweight fusion engine for lightweight processing is transferring the GIS model to a lightweight engine based on a WebGL B / S structure and performing lightweight processing.

[0012] Furthermore, the step of transferring the BIM model to the lightweight fusion engine for lightweight processing is transferring the BIM model to a lightweight engine of a B / S structure based on WebGL and performing lightweight processing.

[0013] Furthermore, the superposition of the BIM and GIS models includes the following steps:

[0014] In a lightweight engine based on WebGL, the 3D real-scene model of drone photography is fused with the BIM model in a specified coordinate system to obtain a complete BIM+GIS model and related data sets.

[0015] Furthermore, the height difference of the GIS model terrain within the projection range of the BIM model is calculated using Cesium, which is the height difference between the terrain and each position of the bottom of the cabin in the superposition of the BIM and GIS models. Cesium is used to perform specified calculations, that is, taking the physical center of each support leg as the reference point, and calculating the distance from the ground to the bottom of the cabin at that point, thereby obtaining the height to which the support leg should be adjusted.

[0016] Furthermore, the system automatically numbers each leg according to the calculation result and pre-adjusts the height of each leg in the factory, and forms a corresponding form according to the Cesium calculation result to provide data for adjusting the height of the legs in the factory.

[0017] Furthermore, the GIS data includes the geographical location of the deployment site and an accurate surface model of the site. The horizontal error of the geographical location of the deployment site and the accurate surface model of the site is ±1 cm, and the vertical error is ±1.5 cm.

[0018] Furthermore, the acquisition of oblique photography GIS data of the target site for rapid deployment of shelters is to acquire GIS data of the location for rapid deployment of shelters by using oblique photography technology of unmanned aerial vehicles.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. A method for pre-adjusting the support legs for rapid deployment of shelters. Based on GIS+BIM technology, the height of the shelter from the ground is calculated and the height of the support legs is pre-adjusted in the factory in advance, which solves the problem that the existing support legs need to be adjusted on site when in use;

[0021] 2. A method for pre-adjusting the legs suitable for rapid deployment of shelters. The GIS+BIM model is designed to calculate the leg height by superimposing it. The inner legs are numbered and pre-adjusted in the factory according to the calculated leg height. When deployed, only minor adjustments are required before the shelter can be put into use, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0028] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0029] See also Figure 1-5 A method for pre-adjusting support legs for rapid deployment of shelters comprises the following steps:

[0030] Obtain oblique photography GIS data of the target site for rapid deployment of shelters and build a GIS model; Figure 1 As shown;

[0031] The GIS model is transferred to the lightweight fusion engine for lightweight processing;

[0032] The BIM model is transferred to the lightweight fusion engine for lightweight processing and superimposed with GIS and BIM models; Figure 2 As shown; the distance between the corresponding point in the GIS model and the unified plane of the BIM model is calculated through the support leg coordinates located by the BIM model, and the height of the BIM bottom surface from the ground at each support leg coordinate is determined, thereby calculating the pre-adjusted height of each support leg.

[0033] Use Cesium to calculate the height difference of the GIS model terrain within the BIM model projection range. If the height difference is within the range of the support leg lifting adjustment, take the physical center of each support leg as the reference point, calculate the distance from the ground to the bottom of the warehouse at that point, and obtain the height that the support leg should be adjusted to; Figure 3 and Figure 4 As shown;

[0034] In the factory, each leg is pre-adjusted to a certain height and numbered according to the calculation results, so that it can be quickly called up and adjusted during subsequent deployment. Figure 5 The height is pre-adjusted in the factory according to the leg number and adjustment height. When deployed on site, only the legs need to be fine-tuned to meet the requirements, greatly speeding up the project progress.

[0035] The GIS model is transferred into the lightweight fusion engine for lightweight processing, that is, the GIS model is transferred into the lightweight engine of the B / S structure based on WebGL and then lightweight processed.

[0036] The BIM model is transferred into the lightweight fusion engine for lightweight processing, that is, the BIM model is transferred into the lightweight engine of the B / S structure based on WebGL and then lightweight processed.

[0037] Overlaying BIM and GIS models involves the following steps:

[0038] In a lightweight engine based on WebGL, the 3D real-scene model of drone photography is fused with the BIM model in a specified coordinate system to obtain a complete BIM+GIS model and related data sets.

[0039] Cesium is used to calculate the height difference of the GIS model terrain within the projection range of the BIM model. In order to obtain the height difference between the terrain and each position of the bottom of the cabin in the superposition of the BIM and GIS models, Cesium is used to perform the specified calculation, that is, taking the physical center of each support leg as the reference point, the distance from the ground to the bottom of the cabin at that point is calculated, so as to obtain the height that the support leg should be adjusted to.

[0040] In the factory, the height of each leg is pre-adjusted and numbered according to the calculation results. The system automatically numbers each leg and forms a corresponding form based on the Cesium calculation results to provide data for adjusting the leg height in the factory.

[0041] GIS data includes the geographic location of the deployment site and the precise surface model of the site. The horizontal error of the geographic location of the deployment site and the precise surface model of the site is ±1cm, and the vertical error is ±1.5cm.

[0042] Obtaining oblique photography GIS data of the target site for rapid deployment of shelters is to obtain GIS data of the location for rapid deployment of shelters through unmanned aerial vehicle oblique photography technology.

[0043] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
